8 Claims.

This invention relates to shingles made of sheet metal for use in covering roofs and in some cases the sides or walls of dwellings.

An object of the invention is to provide a shingle which is locked to adjacent shingles on both sides, as well as on the top and bottom, so as to make each shingle secure from damage by high winds of hurricane proportions, but the invention in its broadest aspect is not limited to the four sided look, as it may include the top and bottom lock only.

Another object of the invention is to provide a shingle of the above type which, when properly set in place, prevents the entrance of water in its 16 top, bottom, and sides from driving rain.

A further object of the invention is to provide a shingle which when assembled with other shingles of like type, will provide a very ornamental roof.

The invention has for its special object the production of shadow effects.

An additional object of the invention is the provision of a shingle which, when assembled on a roof, provides a smooth, even surface.

Other objects will appear throughout the specification.

In the drawing:

Figure 1 is a perspective view showing several of the shingles in interlocked position;

Figure 2 is a view taken on the line 22--22 of Figure 1;

Figure 3 is a view taken on the line 23-23 of Figure 1;

Figure 4 is a view similar to Figure 3 but showing the adjoining edges of two shingles prior to being assembled;

Figure 5 is a detailed plan view of the upper right hand corner of one of the shingles;

Figure 6 is a detailed plan view of the lower right hand corner of one of the shingles;

Figure 7 is a perspective view of the structure shown in Figure 5; and

Figure 8 is a perspective view of the structure shown in Figure 6.

Figures 1 to 8, inclusive, illustrate the embodiment of my invention.

The shingles are intended to be laid upon a flat surface such as a roof covered with tar paper which has been laid upon the flat boards forming the base of the roof (not shown) but in some instances may be used with a stepped roof formed of sheeting boards such as shown at H) in Figure 2.

In this form, 89 indicates the body portion or 5 field suriace'of the shingle. The rear or upper portion of this shingle makes a U-turn at 10, as shown in Figure 22, and has a forward extension H, an upward extension indicated at 12, a rearward extension 13, a diagonal extension 14, and a nailing extension 15, which latter may be 5 1 provided with holes. 16 through which the usual nails are driven into the supporting surface located therebelow. The forward edge, as indicated at 11 extends downwardly, and has a rearwardly extending tongue 18 which fits within a space 10 provided between the upper part of the body portion 69 and the forward extension H, as shown in Figure 2.

Referring to Figures 3 and 4, the right side edge I9 is provided with a U-turn 80, a side ex- 15 tension 8|, a second U-turn 82, a bottom extension 83, which is provided with a depression or valley 84, and a tongue 85. The left side edge 86 is provided with a valley 8! and a tongue 88. The upper right hand corner, as shown in Figure 5, is 20 provided with a cut-out portion 89. The extending tongue is provided with a U-turn and a forward extension 9|.

Referring to Figure '7, the left side of the extension 9| is provided with a double U-turn 92, 25 93, where it joins with the forward extension 1|. Tongue 85 is provided with a downward extension 94 and a double U-turn 95, 96, where it joins with the forward edge of the body portion.

One of the principal advantages of the third 30 embodiment is to provide an air space 91 (Figure 2). This space forms an upright triangle, the apex being defined by a vertical line drawn from approximately the U-turn 10 up to the under side of the rearward extension 13. The base of said 35 triangle would be the flat surface upon which the shingles are laid, and the hypotenuse would be roughly defined by the under surface of the rearward extension 13, and the under surface of the field 69 which lies directly above said rear- 40 ward extension (see Figure 2).

The hypotenuse and base meet at approximately the U-turn 90, the under side of said U- turn resting upon the supporting surface. The forward edge 88' of the tongue 88 is tipped slight- 45 ly upward so as to bind against the under portion of the side extension 8! to prevent water entering beneath said extension, and the troughs 81 and 84 are slightly spaced from each other, as indicated in Figure 3, to prevent water flowing 50 to the right as shown in that figure.

A shadow effect is produced by the upward extension 11. I

Due to the triangular air spaces provided under each tile, this third embodiment should insure a 5 cooler interior for the house it forms the roof thereof. The locking joints at the top, bottom, and sides provide joints which become actually tighter during storms where the wind and water pressure is high, or where the wind reaches hurricane intensity. The trough-like joints forming the engaging means for the side edges, when viewed from a distance, give an appearance of a fiat slab tile roof. The advantages therefore of the third embodiment are, that it may be laid on a fiat surface, which is cheaper to construct than the shingle surface shown in Figure 2; an air insulating space is provided between the lower surface of the shingles and the upper supporting fiat surface of the roof; the roof provides a shadow effect; and it tends to become tighter under strain, such as would be caused by high winds, either with or without heavy rainfall.

A very decorative roof may be formed by using any one of the embodiments illustrated and described. Moreover, such roof is waterproof and hurricane proof, as the shingles will remain on the roof as long as the roof remains on the house. Such shingles may be economically manufactured, as each of them is made from a single piece of metal, with the exception of the gore pieces used in the hips and valleys.

It is to be expressly understood that this invention is not to be limited to a top and bottom lock for sheet metal shingles, in combination with the specific side lock shown in Figure 3, and other figures, but may embrace a top and bottom lock for shingles per se, or a side lock, per se.

The foregoing description and drawing are understood to be for illustrative purposes only, and it is further understood that the invention is capable of various modifications. I desire to be limited, therefore, in the practice of my invention only to the extent as defined by the appended claims.
